109355-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109355-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,3,5 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109355-78:
(8*1)+(7*0)+(6*9)+(5*3)+(4*5)+(3*5)+(2*7)+(1*8)=134
134 % 10 = 4
So 109355-78-4 is a valid CAS Registry Number.
